: Is This Going To Be Enough Radiator for my 454?

Hey guys, as some of you know I am installing a 454 into my little Datsun 280z. I used to run a 383 with this radiator and it did great: https://shell7.tdl.com/~jags/Pages/Parts_DATZ_Radiator.html

I am worried that with the increased displacement, the old radiator won't be able to do the job.

My second option is to run a universal type like this:

I will be running a flex-fan with a home-made shroud, which is the same setup as before.
